While record low fatality rates indicate that today?s cars are safer than ever, the latest crash test results confirm that some models still do a better job than others at protecting their occupants in a serious collision.
Thanks in large part to advancements in automotive engineering and mandated safety features like airbags and electronic stability control (along with stricter seatbelt and impaired/distracted driving laws) traffic fatalities have dropped by 25 percent over the last five years. Unfortunately they still accounted for a total of 32,788 deaths in 2010 according to the National Highway Traffic Safety Administration.
Nowhere is choosing the safest auto available more important than when shopping for a small car, where every advantage is essential. That?s because the laws of physics dictate that, all else being equal, a smaller and lighter vehicle will tend to fare worse in a crash than a larger and heavier model. Compacts and subcompacts are becoming increasingly popular among cash-strapped buyers and empty nesters looking to downsize their rides; J.D. Power and Associates says they?re on pace to outsell midsize entries for the first time in nearly two decades.

Fortunately, those shopping for a small car for themselves or younger members of the family will find a burgeoning selection of models from which to choose that are rated as ?Top Safety Picks? by the Insurance Institute for Highway Safety (IIHS). To qualify, a car must garner top scores across the board for performance in front, side, rollover and rear-end crashes based on ratings determined by the IIHS? evaluations. Vehicles are classified in each category on a basis of ?good,? ?acceptable,? ?marginal? or ?poor? performance.
?For the second year running a record number of models qualify as Top Safety Picks,? says IIHS president Adrian Lund. ?It?s tough to win, and we commend auto manufacturers for making safety a top priority.?
For testing a car?s crashworthiness in a frontal collision, the IIHS performs ?offset barrier? tests at 40 mph, using average-size male test dummies. Here, only part of a vehicle?s front end hits a deformable barrier, which simulates the front of another vehicle. This test is said to provide a good indication of how well a vehicle?s structure will be maintained in a crash to protect its occupants, particularly against injuries to the lower extremities.

The IIHS? side-impact test approximates the front end of a full-size pickup truck or SUV striking the passenger?s side of a vehicle at 31 mph. The potential for injuries are measured using test dummies that approximate a small female or adolescent child. The IIHS uses smaller dummies here because its data suggests that women are more likely than men to suffer serious head injuries in a side impact collision.
Rollover protection ratings are based on roof crush tests. To earn a ?Good? rating here, a vehicle?s roof must be able to withstand a force of four times its own weight before reaching five inches of crush depth. The IIHS estimates that such roofs reduce the risk of serious and fatal injury in single-vehicle rollovers by about 50 percent compared with those that merely meet the federal minimum requirement for crush resistance.
While deaths from rear-end crashes are relatively low they?re one of the most common causes for whiplash-type neck injuries, which result from the sudden jerking forward of an occupant?s head and torso. The IIHS simulates rear-end collisions using a combination of static measurements and active crash-dummy testing to determine how well the vehicles? seats and head rests support their occupants in a rear-end collision at 20 mph.

The IIHS? list of Top Safety Picks among small cars with sticker prices that start at under $20,000 (including destination charges) has grown to 20 selections for 2012, up from just 12 a year ago. Newly added recommendations this year include the Chevrolet Sonic, Fiat 500, Ford Focus, Honda Fit and Insight, Hyundai Elantra, Scion xD and Toyota Yaris.
